TECHNICAL FIELD

The present invention relates to a door guide frame of detachable segment structure for guiding the sliding movement of a roller device which supports a sliding window and provides a sliding opening/closing operation and, more particularly, to a sliding window installation structure which is capable of: stably supporting and moving a sliding window or a horizontal sliding window (hereinafter, generally referred to as a “sliding window”) on a bottom surface and a top surface on which the sliding window is installed; reducing an installation space by minimizing the size of a door guide frame and a roller device for supporting a heavy sliding window, thereby obtaining a wider open view when applied to a window; and employing a structure comprising a door guide frame of detachable segment structure which prevents a door guide rail from protruding upward from the bottom surface of a window frame so as to prevent occurrence of a passage obstacle which may be caused when the door guide rail protrudes on a moving passage while the window is opened, as well as to provide a good aesthetic appearance, thereby providing excellent applicability to various fields.

Background Art (Prior Art)

The applicant of the present application has proposed an invention disclosed in Korean Patent Application No. 10-2012-0047789 (filed on May 26, 2012) with respect to a sliding window installation structure including a door guide frame of such a separable and detachable segment structure. This Korean patent application has been disclosed in Korean Patent Laid-Open Publication No. 10-2013-0124444 (published on Nov. 14, 2013) and Korean Patent Publication No. 10-1367835 (issued on Mar. 3, 2014) It has also been published as WIPO Open Publication WO2013/168943A1 (published Nov. 14, 2014) and US Patent Application Laid-Open No. 2015-0121764 A1 (published May 7, 2015).

In the sliding window installation structure according to the prior art of the applicant of the present application, as shown in FIGS. 1 to 4 attached herewith, there is shown a door guide frame 100 for guiding a sliding window 400 at the inner and outer sides (front side and back side/inner and outer surfaces) of the sliding window 400, in which a pocket guide 130 is detachably attached to a main body portion 120 of the door guide frame 100. The pocket guide 130 includes a pocket guide segment (130; 130{circle around (a)} or 130{circle around (b)}; 130-1, 130-2, 130-3, and 130-4) detachable from the main body portion 120 of the door guide frame 100. Therefore, there is shown the door guide frame 100 having a structure in which the pocket guide segments (130; 130{circle around (a)} or 130{circle around (b)}) are detachably and continuously installed on both inner and outer surfaces of the sliding window 400 along a moving direction of a roller guide rail 110. However, an aluminum material can be generally used as a basic material for providing the door guide frame 100 having a detachable segment structure that forms such a structure. In the case of such an aluminum material, as shown in the cross-sectional view of the operating state of FIGS. 1 to 4 and in a partially exploded perspective view of FIG. 2 (a perspective view at a B-B′ broken line location of FIG. 4), it is more advantageous to employ a structure in which the main body portion 120 of the door guide frame 100 is divided into two portions of the inner side and the outer side of the window and a heat bridge blocking member 120m (thermal bridge breaker) is disposed in a middle portion between the two portions. Moreover, a leg region 130m may be preferably formed of a heat-transmission-blocking material separated from a remaining upper cap region 130a made of aluminum.

However, when the main body portion 120 of the door guide frame 100 is arranged into two parts of an outer main body portion 120-out and an inner main body portion 120-in while the heat bridge blocking member 120m is disposed in the middle of the two parts as shown in FIG. 5, four pocket guide segments (130: 130{circle around (a)} or 130{circle around (b)}; 130-1, 130-2, 130-3, and 130-4) should be detachably installed on the main body portion 120 of the door guide frame 100, i.e. on the base surfaces of the outer main body portion 120-out and the inner main body portion 120-in. To this end, a partition wall 121 is protruded and formed on both sides of the roller guide rail 110 along the moving direction of the roller guide rail 110 to form a receiving portion 122 into which the pocket guide segment 130 can be inserted. Thereby, a leg portion of a first pocket guide segment 130-1 is inserted into an inner side of the receiving portion 122 of the inner main body portion 120-in, a leg portion of a second pocket guide segment 130-2 is inserted into an outer side of the receiving portion 122 of the inner main body portion 120-in, a leg portion of a third pocket guide segment 130-3 is inserted into an inner side of the receiving portion 122 of the outer main body portion 120-out, and a leg portion of a fourth pocket guide segment 130-4 is received into an outer side of the receiving portion 122 of the outer main body portion 120-out, respectively.

FIGS. 6, 7 and 8 show an application example in which the structure shown in FIGS. 1 to 4 and 5 is designed and manufactured as an actual product. In this application example, not only the main body portion 120 of the door guide frame 100, but also a vertical guide frame 101 on both sides is also made to adopt a heat insulating structure in which an inner frame and an outer frame are connected to each other by a thermal bridge blocking member 101m disposed in the middle region between the inner frame and the outer frame, and in a vertical reinforcing member 420 having an enlarged section (a section having a thickness larger than a thickness of the glass) for compensating the lateral bending stiffness of the glass 410 is formed on both sides of a glass 410 constituting the sliding window 400, furthermore provides a specific difference in that a steel reinforcing plate 422 for reinforcing the rigidity is inserted into the inside of the vertical reinforcing member 420.

In the door guide frame of the separable and detachable segment structure for sliding windows according to the prior art described above, in the case of a first pocket guide segment 130-1 being accommodated in the inner side surface of the inner main body portion 120-in, and in the case of a fourth pocket guide segment 130-4 being accommodated in the outer surface of the outer main body portion 120-out, the entirety may be formed of an aluminum material (see FIG. 5), or only the leg portion thereof may be formed as a thermal bridge blocking member (see FIG. 6 and FIG. 7). These are housed in the receiving portion 122 of the main body portion 120 of the door guide frame 100 of the aluminum material with the two inner and outer leg portions at the lower portion to form a good supporting state as shown in the figure. On the other hand, as shown in FIG. 8, in the case of the second pocket guide segment 130-2 being accommodated in the outer surface of the inner main body portion 120-in and in the case of the third pocket guide segment 130-3 being accommodated in the inner surface of the outer main body portion 120-out, since the lower leg region 130m, formed by the heat bridge member being separated from the upper cap region 130a of the aluminum material, should be located on the heat bridge blocking member 120m connecting the inner main body portion 120-in and the outer main body portion 120-out of the main body portion 120 of the door guide frame 100, it is difficult to expect a good supporting force. Also, it is difficult to provide suitable fastening means (fitting engagement) to the thermal bridge blocking member 120m between them (making it difficult to form with the fitting engagement). Therefore, there is a high possibility that a mounting clearance is generated in a connecting part contact-K between the first pocket guide segment 130-2 and the third pocket guide segment 130-3, and if the first pocket guide segment 130-2 and the third pocket guide segment 130-3 are made with a little tolerance margin to reduce the possibility of such clearance, accordingly, it is difficult to install the other one in a state in which one of the two is installed first, and thus a poor installation condition such as the incline of the upper cap region 130a occurs.

Further, when such a poor workability is caused, friction noise due to inadequate excessive friction with the accessory guide rollers 457 provided on the side of the roller member 450 under the sliding window 400 may occur.
